[其它]Steady-state performance of synchronous generators with AC and DC stator connections considering sat

Abstract—Synchronous generators with ac and dc stator connections a r#p7N  
are widely used in systems where simultaneous ac and dc ;2vHdN  
power supplies are needed. For these systems the voltage harmonic Elt=/,v`!  
distortion of ac voltage, dc voltage ripple and dc voltage varying >Rw[x  
range are of special interest. Because of the commutation of rectifier dE*n

and the saturation of magnetic circuit, the accurate calculation i51
